KieranTimberlake, an architectural firm based in Philadelphia, is a recognized leader of the "green" architecture movement in the U.S. As this film illustrates, its founders Stephen Kieran and James Timberlake have been developing innovative means to combine sustainable design principles with off-site construction for the mass customization of houses. The firm’s Loblolly House, built in the Chesapeake Bay area of Maryland in 2007, and the Cellophane House, a specially-commissioned design executed for an exhibition at The Museum of Modern Art in 2008, serve as outstanding examples of the firm’s research-based approach.
